How to Spot a Rug Pull on Solana Before It Happens
Rug pulls are the biggest risk in Solana DeFi. Learn the warning signs — from contract permissions to holder concentration — so you can avoid losing your capital.
What Is a Rug Pull?
A rug pull occurs when a token creator removes liquidity, mints unlimited tokens, or dumps a large pre-held supply — crashing the price and leaving holders with worthless tokens. It's the most common scam in DeFi, and Solana's low fees make it easy for scammers to launch dozens of rug tokens per day.
Warning Sign: Mint Authority Not Revoked
If the token creator still has mint authority, they can create unlimited new tokens at any time, instantly diluting your holdings to zero. Always check whether mint authority has been revoked before buying. CTools checks this automatically in every analysis.
Warning Sign: Extreme Holder Concentration
When the top 10 wallets hold more than 50-60% of the supply, one or two entities effectively control the market. They can dump at any moment. CTools flags holder concentration and adjusts the risk score accordingly.
Warning Sign: Very Low Liquidity
Tokens with less than $5,000 in liquidity are extremely dangerous. Even if the price looks good on paper, you won't be able to sell without massive slippage. Many rug tokens intentionally keep liquidity low so they can pull it with minimal capital.
Warning Sign: Token Age Under 2 Hours
Most rug pulls happen within the first few hours of a token's life. While not every new token is a scam, tokens under 2 hours old carry significantly higher risk. CTools factors token age into every verdict and caps confidence for very new tokens.
How to Protect Yourself
Use CTools before every buy. Paste the mint address and check the verdict. If you see Avoid with reasons like 'High rug probability', 'Extreme holder concentration', or 'Mint authority not revoked', stay away. No opportunity is worth the risk of a complete loss.
